R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-8
Unimplemented:
Read as ‘0’
bit 7
WFT
: Waveform Type Select bit
1
= Type-B waveform (phase changes on each frame boundary)
0
= Type-A waveform (phase changes within each common type)
bit 6
BIASMD
: Bias Mode Select bit
When LMUX<2:0> = 000 or 011 through 111:
0
0
= Static Bias mode (do not set this bit to ‘1’)
When LMUX<2:0> = 001 or 010:
1
1
= 1/2 Bias mode
0
= 1/3 Bias mode
bit 5
LCDA
: LCD Active Status bit
1
= LCD driver module is active
0
= LCD driver module is inactive
